IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 52,18 3, dated January 23, 1866.

To all whom it may concern:

Be it known that I, STEPHEN Gr. MILLS, of Fort Des Moines, in the county of Polk and State of Iowa, have made new and useful Improvements in Cultivators and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same sufficient to enable one skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, which are made part of this specification, and in which- Figure l is a rear elevation of the machine. Fig. 2 is a plan or top view of the machine.

This improvement consists in the arrangement of the two vertically and laterally adjustable double-shovel plows, including the combination ot'devices by which they are supported, enabled to traverse laterally, and elevated at will.

In the drawings, A is the axle and B the wheel. G are the pieces shaped like ordinary \vagonhounds, and forming the frame of the cultivatorin connection with theforward piece, D, which is secured to the tongue E, the latter being also fastened into the axle A.

Hinged at the intersection of the pieces 0 O with the piece D are two double-shovel plowbeams, F F, which carry beams G G and shovels or shares H H, and have vertical standards I I, which ascend through guides J J attached to the axle, and are united by a crosspiece, 0, which preserves their relative distance from each other.

M is a bridge-piece passing across between the pieces 0 O of the frame, and serving to support the plow-beams by means of the chains K K and the wheels LL, which have grooved peripheries and traverse the short angular tracks on the upper edge of the bridge M as the plow-beams are pushed laterally by means of the lever N, which is pivoted on the bridge and attached at its forward end to the bar 0. ,The seat-board It is attached to the frame by the pieces S S, and when down the arms 'I T occupy the slots U U in the frame 0 (l; but the seat-board may be turnednp, as in Fig. 1, so as to be out of the way when the driver of the team walks behindithe machine. Fig. 2 shows the foot-board partially raised.

When the driver walks he operates the plows by means of the lever N, so far asflateral motion is concerned; but when he rides the lateral motion may be obtained by the lever or pressure ofthe feet on the plow-beams. The vertical adjustment is due to the chains KjK. I/Vhen riding, if one of the doublejjplows chokes, by depressing the lever and settinggjthe foot on the other plow-beam the choked plow is raised and the accumulated trash isgallowed to drop.

Having described myinvention, whatIclaim therein as newfandgdesire to securezby Letters Patent, is-

The arrangementof the pair ot'double-shovel plow-beams F, standards I, guides J, chains E, wheels L, bridge M, bar 0, lever N, and shifting seat R, substantially as described and represented.
